O’Hare’s South Tower Under Construction

Construction began recently on the south satellite control tower building at Chicago O’Hare International Airport. The facility is to monitor traffic that will primarily use the airport’s new Runway 28L/10R, which is to open in the fall of 2015. The top of the tower-cab antennas will rise 219 feet agl, with the controller’s-eye-view inside the cab set at 194 feet agl. The $28 million facility is expected to operate from 6 a.m. to 10 p.m. local time.
